防火墙
1.查看下防火墙的状态:systemctl status firewalld systemctl stop firewalld 关闭 systemctl
disable firewalld 开机不启永久关闭 2.查看已开放的端口 firewall-cmd --zone=public --list-ports
firewall-cmd --permanent --zone=public --add-port=8484/tcp 3.重启防火墙 firewall-cmd
--reload
网关
网卡的目录 /etc/sysconfig/network-scripts 直接给 网卡分配ip ifconfig ens33 192.168.11.12
三、文件快捷键
ln -s 文件路径 别名 ln -s /usr/local/nginx/conf/ nginxcon # cd nginxcon
可以进入nginx配置文件
四 alias 别名
可以简化你的操作 (需要一起执行的命令 放一块)
alias viens33="vi /etc/sysconfig/network-scripts/ifcfg-ens33" #可以用一个命令解决
查看所有的
五压缩 zip tar
添加压缩包 zip 文件.zip 文件
添加压缩文件 zip -r xxx.zip /user/local/mysql #解压 -o 是覆盖 unzip -o xx.zip
tar -cvf xxx.tar /path/to/folder #添加压缩 tar -xvf xxx.tar /path/to/folder #解压
dx 进程号 -查看目录
[root@localhost network-scripts]# pwdx 4923 4923: /usr/local/mysql/data
